To aZZ whom it may concern.-

Be it known that we, FRANK DAWSON. S12, and FRANK Dawson, Jr., of Williamsport, in the countyot Lycoining and State of Pennsylvania, have invented a new and useful In1- provement in (Jar-Starters, and we do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Our invention relates to certain improve ments upon the car-starter described in Letters Patent No. 300,698, granted to Dawson and Holleyhead, June 17, 188i; and our object is to reduce the original number of parts, to

simplify their construction, and consequently effect a greater economy of first cost, and at the same time lessen frictional wear and exclude all dust and dirt from entrance to the axle and the bearings of the several parts.

The novelty of these improvements consists, mainly, in the construction and arrangement of the lever-clutch and its attachments, and in their combination with other parts of the de vice, all as more fully hereinafter described, and pointed out in the claims.

For the better understanding of these improvements attention is invited to the accompanying drawings, wherein is illustrated only that portion of the car-starter which embraces our improvements, and in which-- Figure 1 is a plan of thedriving-wheel and lever-clutch; Fig. 2, a side view with one-half of the driving-wheel removed; and Fig. 3, a detail of the lever-clutch and the collar to which it is attached.

As illustrated, A denotes the axle, upon which is placed adriving-wheel, B, consisting of two separate sections, to (teach madein two equal parts, I) b, so as to be readilyplaced up on or removed from the axle. Each sect-ion a of the wheel Bis recessed on its interior to form a flange or rim, 0, around its periphery, and the parts b b, composing the sections of the wheel, are each provided on one side with an equal section of a hub, d, and a clamping arm, 0, which parts are secured together and are made to closely embrace the axle by means of screws (1 d, as shown. The sections a a,as

thus constructed,are placed upon the axle, so as to leave an intervening space, f, between their flanges or rims c, and are firmly held in their positions by means of set-screws 8, pass ing through the sides of the hubs d (i into the axle. t

Both sections of the drivingwheel have an interior hub, r thethickness of which is about twice that of the hubs d, and one of which is provided with an additional smaller hub, g, which supports a collar, 0, madein two equal parts, having cars h h, secured together by screws h h, passing through said cars. This collar is placed loosely over the hub 9', so as to have easy rotation thereon, and is restrained from lateral movement by the ends of the interior hubs, g g. This loose collar is also provided with a radial arm, i, and a segment, i, which, together with the cars h h, extend out through the space f, between the sections a a, to the periphery of the flanges or rims cc, and are of a thickness about equal to the width of spacef. This spaccf is covered,for the purpose of excluding all dust and dirt, by means of a casing, D, secured to the ends of the ears and arms of the loose collar 0, and partly inclosing the external periphery of the drivingwheel, with a portion cut out to give free movement to a lever-clutch, E, and having an oil box or chamber, D, opening at its bottom into the space f, for supplying a lubricant to the bearings of the several parts located between the sections of the driving-wheel.

This lever-clutch E, above referred to, has a lever-arm, Z, two jaws, Z Z, which embrace the flanges or rims c c of the driving-wheel. two hooks, m m, conforming in size to said flanges or rims, and acentral lug or extension, n, pivoted by means of a pin, 0, between two ears, 1) p, which are secured to the loose collar just above its radial segment i.

To the outer end of the lever-arm Z is attached a chain, E, which has connection with mechanism upon the car-bottomlike, or substantiallylikc, that described in the patent hereinbefore mentioned, and the operation of this mechanism upon the lever-arm transmits movement to the clutch and its several connections and causes them to act substantiallylike thecorresponding parts of the device described in said former patent.

The advantages and the benefits derived from our improvements are that but little or no dust can enter to the bearings of the several parts, and at the same time better facilities are instituted for lubrication.

By making the driving-wheel in two removable sections the lever-clutch and its loose collar maybe removed and replaced by merely slipping one of said sections off and on its axle without separating the two parts of said sections, as was necessarily done in our other device, and that the employment of but one collar greatly lessens the friction and enables us to effect greater economyin the cost originally involved.

WVe claim- 1. The combination, in a car-starter, of a driving-wheel made in two removable sections, a loose collar mounted between said sections, and a lever-clutch pivoted to said collar, sub 'stantially as described.

2. The combination, in a car-starter, of a driving-wheel made in two removable sections, a loose collar mounted between said sections, with a casing partly inclosing the periphery of the driving-wheel. and a lever-clutch pivoted to said collar andhaving jaws embracing the rim-fianges of said sections, substantially as described.

3. A lever-clutch, ZE, for a car-starter, having two jaws, Z Z, two hooks, m m, and a central lug or extension, n, substantially as described.

4. The combination, in a car-starter, of a driving-wheel made in two removable sections,

a a, each made in two equal parts, I) b, with lateral rim-flanges e c, and a lever-clutch, E, having two jaws, Z Z, hooks m m, and a lug or extension, n, substantially as and for the purpose set forth.

5. The combination, in a car-starter, of the driving-wheel B, made in two removable sections, the loose collar 0, made in two parts,

mounted between said sections, and thelever- FRANK DAWSON, SR. FRANK DAWSON, JR.
